Several years ago we had a traffic reporter (recent FW transition) in a R-22 respond to a model rocket climbing up at him by pushing the nose over. Result was mast bump, tail boom speration, rotor blade seperation and fatality.
yep..."bunting" is a SWTI term for terrain masking down the back side of a cliff/mountain.
Wait, so what happened? On top of mast-bumping, did the main rotor strike the tail boom causing separation? That's a horrible fucking day. Basically turn flying machine into beveled brick.
What, do you want to ride my short bus? :icon_winkI feel special...I got my own thread![]()

It's not like the mast bump hadn't already screwed him over. Once the rotors have left the helo, there's not much more you can do. The fact that the rotors took the tail with it when it left just means that a little bit less of your helo will accompany you to your crash site.
Also, there are some helos where excessive aft cyclic and low collective can cause the MR to contact the tail boom. When I was at HSC-3, there was a IGB cover with a gash in it from a MR blade. Came within inches of hitting the IGB. H-3 and Hind are also notorious for this sort of behavior.
So how do you mitigate low-g conditions during terrain masking? I know you want to cross cliffs/peaks at a diagonal to reduce the magnitude of the pitch change, but is there an accelerometer or does the pilot's butt serve as that instrument to determine .5g?
I did just sit through helo aero, so that actually all makes sense. I just wasn't thinking in 3-D as far as using roll to increase descent rate.
And I just realized the semi-articulated fleet aircraft are going away, anyway.
